1.C.111.1.12
Dendritic cell natural killer lectin group receptor 1, DNGR-1, of 238 aas and 1 N-terminal TMS. It is also called C-type lectin domain family 9 member A (Cle9a). It functions as an endocytic receptor on a small subset of myeloid cells specialized for the uptake and processing of material from dead cells (Sancho et al. 2009). It recognizes filamentous form of actin in association with particular actin-binding domains of cytoskeletal proteins, including spectrin, exposed when cell membranes are damaged. It mediates the cross-presentation of dead-cell associated antigens in a Syk-dependent manner (Sancho et al. 2009; ). DNGR-1 is a receptor expressed by certain dendritic cell (DC) subsets and by DC precursors in the mouse. It possesses a C-type lectin-like domain (CTLD) followed by a poorly characterized neck region coupled to a transmembrane region and short intracellular tail. The CTLD of DNGR-1 binds F-actin exposed by dead cell corpses and causes the receptor to signal and potentiate cross-presentation of dead cell-associated antigens by DCs.The neck region of DNGR-1 is an integral receptor component that senses receptor progression through the endocytic pathway and has evolved to maximize extraction of antigens from cell corpses (HanĨ et al. 2016).
